Life is a battle for survival. Every animal wants to eat, and the thing that they want to eat... well that can be another animal. This dance between predators and prey creates what we call a food web - a kind of map showing who eats who. This map is enormously complex, varies from place to place, and in reality is always in motion.
Take a glimpse of just a small part of the western Atlantic food web through the eyes and words of American author Isaac McLellan in his 1897 poem The Bluefish
